CONSTRUCTION OF GLAZED ROOFS.

SPECIFICATION forming part of Letters Patent N o. 270,337, dated January 9, 1883. Application filed June 19, 1582. (No model.) Patented in England July 15, 1880, No. 2,922, and in France July 17, 1880, No. 137,824,

To all whom it may concern:

Be itknown that we, JOHN EDGCUMBE BEN DLEand FRANK BULLEN RENDLE, subjects ot' the Queen of Great Britain, residing at No. 3 lestminster Chambers, Victoria Street, in the city of Westminster, England, and DAVID HENRY WILsoN, a subject of the Queen of Great Britain, residing at H) res, Var, in the Republic of France, are the executors of the last will and testament of WILLIAM EDG- cUMBn RENDLE, deceased, late a subject of the Queen of Great Britain, who invented certain new and useful Improvementsin the Gonstruction of Glazed Roofs and other Glazed Structures, (for whichthe said WILLIAM EDG- cUMBn RENDLE received Letters Patent in Great Britain, No. 2,922, dated July l5, 1880, and in France, No. 137,824, dated July 17,

1880, (of which the following` is a specification.

rlhis invention relates to improvements in glazed structures of the class shown in United States Letters Patent No. 224,608, of February 17, 188i); and in accordance with these improvements sheets of glass, instead of being secured to horizontal purlins, as before, (see said Patent No. 224,6US,) are attached to such purlins in the following manner: The upper ends ofthe sheets of glass in a row rest upon the face or suitably-inclined outer surface of one horizontal purlin, while the lower ends of these sheets of glass are received in troughs formed iu angularly-bent sheetmetal bars secured to another horizontal purlin by being attached to the upper side thereof-that is to say, to a surface ofthe purlin ata rightangle with its face--upon which the upper ends of the next lower row of sheets of glass rest, and so that the troughs of the bent metal bars will be over or rest upon the upper ends of said lower row cf sheets. By forming each of the bars by a single bend into the desired angular shape one portion or surface ofthe bar forms a side Bange or attaching-shank, and the other portion or surface forms a fiat face or outer support, against or upon which the back of the lower end of a sheet of glass rests. ln addition to this supporting-surface, each of the bars is provided with the trough for the lower end of a sheet of `ela-ss by being bent back at right angles and then having three more right-angled bends formed in it, so as to provide, as' it were, a partially-open rectangular tube, or partially closed over trough along the bottom of each bar. The bottom of this tube or trough rests upon the surface of top end of the sheets ol" glass and holds them down, being made flat, and so as to afford a sufficiently-broad surface for proper action.

The sheets of glass at their bottom end are overlapped by the last bend ofthe sheet metal of which the horizontal sheet-metal bar is formed, and which covers or partially covers the trough which is along the'bottom of thatA bar, as above mentioned. The sheets of glass are thus prevented from slipping down.

Guttenbars are interposed between the adjacent side edges of the sheets of glass, and

are formed as before, except that instead ofV the gutters heilig curved at bottom and rounded in forni they are now made with lint bottoms and of rectangular form.

The horizontal sheet-metal bars which are attached to the purlins are cut into lengths somewhat shorter than the widthofthe sheets of glass, so that at their ends they may abut against the sides of the bars, which, as just stated, are placed between the side edges of the sheets of glass, and so make a close joint. The troughs at the bottom edge of the hori zontal bars, which are secured to the purlins,

have holes vformed in them, to allow any water which. may flow down into them either from the inner or outer face of the glass to run od' onto the top of the pane of glass below them.

The new horizontal metal bar is adapted for any kind of purlin, either of wood or iron, and is secured by means of screws fastened at the upper side portions of the purlin. Then the glazing-bar is fixed to iron a piece of indiarubber or felt is interposed between the same to prevent contact of the two metals, and can also be placed on the dat surface of the iron to act as a cushion for the upper edges of the glass.

Having thus described the nature of the invention, we will proceed to describe more fully the mannerofpert'orming the same preparatory to a specific designation of the subjecthiatter claimed.

In the drawings, Figure 1 is a plan view. in perspective, ofa portieri of a rootglazed in the above manner, and in which wooden purlins are used. Fig.2 is a. vertical section of the same. Figs. 3 and 4. show cross-sections of similar roofs in which the purlins are of iron of different sections. These are only shown as examples ot the forms of purlin that may be l used; but it is evident that the purlins might be of other sections or l'orms.

The root' or other structure is formed with the requisite numberl ot' horizontal purlins or supports at a distance fiom one another some what less than the length ot' the sheets ot' glass which are to be used. One only ot" these supports is shown at A.

'13 are the sheets of glass. The upper ends of' the sheets ot' glass lie upon the top of the purlins A, and are held down onto them by the bars C, each formed of bent sheet metal, with a trough along one edge and au attaching-shank or downward bend at the other. These bars are secured at their 'shanlts or rightangular tianges bv screws or other fastenings to the upper sides of the purlins, as shown. When the purlin is ot' iron and the bar U of other metal a piece ot india-rubber or felt, D, may be interposed between them and prevent contact ot' the two metals. A similar strip of soft metal might,- also be placed between the tlat surface ofthe purlin and the glass resting upon it, so as to term a cushion tor the glass to lie upon. The bars U, in addition to holding` down the upper end of one sheet of glass onto the purlin, are also, as above stated, formed to support and hold the lower ends ot' the sheet of glass next above it. The way in whit-h the sheet metal ot' which the bar is formed has right-angled bends made in it to effect this objectis clearly shown by the dra win gs.

The partially-closed-over trough formed, as shown, along the bottom of the bar liaslioles (.l formed at intervals through it, so that any water which may run down into the trough, either from the inner or outer lace of the glass, may run ot' onto the top ot the sheet ot' glass below it.

E are the barsot' bent sheet metal interposed between the abutting side edges ofthe sheets of glass. A n end view ot' one ot' these bars is shown at Fig. 5. Each bar E is, as abovestated, t'ormetl with a tlat surtace to cover over the space between the side edges ol two adjoining sheets ot glass, and also to lap over these sheets ot' glass to any extent required. lt is also formed with a stem to descend between the sheets of glass, and also with two troughs-one on either side ot' the stem-and these troughs, in place of being of a rounded I'orm, are made with {iatsides and rectangular,

` so that the ends of the bars U maY abut and fit against them.

The bars E at their upper ends may have the troughs cutaway, so that the bars may be ot' the same length as the sheets ot' glass, and `vet not render it necessary that the purlins should be cut away or recessed for the troughs of these bars to lie in. The bars G are in lengths somewhat shorter than the width of the sheets of glass used, just sutcient to allow of their ends abutting against the bars E, as shown at Fig. 1.

A pin, H, may be passed throughA the stem ot' the bar E, near itslower end, and the ends otthe pin be made to extend into the troughs ot' the bars C, to prevent the bars E trom slippingdownward. l

Fig. G shows a cross-section ot' a small skylight glazed as above described. Figs. 7 and S show how the top and bottom of the skylight root' may be l'ormed. The top and bottom ot' other ridge-roofs similarly glazed may be formed in the same manner. Figs. 9 and l0 show the way in which the vertical bars E may be formed for finishing hips and ends of a roof, respectively.

It should be noticed that, unlike means heretofore employed for supporting the upper and lower ends, respectively, ot' the sheets of' glass in two adjacent rows, so that the attaehing portion of the support llies between the glass and the purlin and has its fastenings *coveredA by Athe glass, the supporting-bar C, Yasherein shown,is secured by fastening-s which are not covered, and so may be readily gotten at with the glass in place. and the upper ends ot a row ot' sheets ot'glass rest upon the purlins instead of upon the securing-bars.

Having thus described the nature of the invention and the manner ot' ptnforming the same, we would have it understood that we claim- 1. 'lhehorizontal bar C, constructed with the right-angular ilaugeor attaching shank and the trough, substantiallyv as and for the purpose described.

2. The combination ot' the horizontal purlins, the horizontal bars provided with the right angular flanges or attaching-shanks secured to the upper sides ot' the purlins and with the troughs, and the rows ot sheets of glass resting at their upper ends upon the purlins beneath the troughs ot' the horizontal bars and at their lower ends held by said troughs, substantially as hereinbefore set torth.

3. The combination ofthe purlins, the angular bars C, having the side tlanges or attaching-Shanks and the glass-supporting surfaces at right angles therewith, the rows otl sheets ot' glass, and the gutter-bars, substantially as and for the purpose hereiubet'ore set l'orth.

4 The combination ot the horizontal bars C, the gutter-bar E, and the pin lil, tor connecting the horizontal bars andthe gutterbar, substantially as hereiubet'ore set forth.
